After the currently used dust cover is assembled at the factory, it is affected by external conditions at the end customer, resulting in the dust cover falling off the panel or being damaged under violent conditions, and it cannot be disassembled and reinstalled or disassembled and replaced with a new cover body, thus affecting the overall product protection. Summary of the Utility Model

[0003] An object of the utility model is to provide a new technical solution for a dust cover to solve the problem that after the dust cover is assembled at the factory, it is affected by external conditions at the end customer, resulting in the dust cover falling off the panel or being damaged under violent conditions, and it cannot be disassembled and reinstalled or disassembled and replaced with a new cover body, thus affecting the overall product protection.

[0004] According to the first aspect of the utility model, there is provided a dust cover which is arranged on the panel of a charging / discharging gun or a charging seat and is used to shield the panel, and includes a cover body, a rotating shaft, a spring and a torsion spring. One side of the cover body is provided with a hinged part, and a through rotating through hole is arranged in the hinged part. At least part of the rotating shaft, the spring and the torsion spring are located in the rotating through hole; two opposite locking holes are arranged on one side of the panel, and two ends of the rotating shaft are respectively inserted and connected with the two locking holes to hingedly connect the cover body to the panel. The rotating shaft includes a stop shaft and a first rotating shaft and a second rotating shaft axially extending from opposite ends of the stop shaft respectively. The spring and the torsion spring are respectively sleeved on the first rotating shaft and the second rotating shaft, and blocking parts for blocking the spring and the torsion spring from detaching are arranged at both ends of the rotating through hole. The depth of the locking hole corresponding to the first rotating shaft is greater than or equal to the lengths of the first rotating shaft and the second rotating shaft in the corresponding locking hole. The rotating shaft axially moves in the rotating through hole under the action of an external force, and the second rotating shaft is separated from the corresponding locking hole, so that the cover body is separated from the connection with the panel.

[0005] Optionally, the rotating through hole is a stepped hole. The stop shaft, the second rotating shaft, the spring and the torsion spring are arranged in the large-diameter end of the stepped hole. At least part of the first rotating shaft passes through the small-diameter end of the stepped hole and is inserted and connected with the corresponding locking hole. The blocking part is the stepped surface of the stepped hole and abuts against one end of the spring.

[0006] Optionally, the torsion spring includes a spring body, a first torsion arm and a second torsion arm connected to the spring body. The spring body is located inside the end with a larger diameter of the stepped hole. The blocking portion further includes a clamping groove provided on the hinge portion and extending circumferentially. The clamping groove communicates with the rotation through hole. The first torsion arm and the second torsion arm extend out of the clamping groove and limit the axial movement of the torsion spring in the rotation through hole.

[0007] Optionally, an installation groove is further formed on the hinge portion from the outside of the hinge portion to the clamping groove. The installation groove communicates with the rotation through hole. The first torsion arm and the second torsion arm enter the clamping groove from the installation groove.

[0008] Optionally, the inner hole of the spring body has a clearance fit with the second rotating shaft.

[0009] Optionally, the spring is a compression spring. One end of the spring body opposite to the first torsion arm and the second torsion arm, and the other end of the spring are respectively abutted against opposite ends of the stop shaft.

[0010] Optionally, the locking hole corresponding to the second rotating shaft is a through hole. A tool is inserted into the through hole to abut against the second rotating shaft and an external force is applied to axially move the rotating shaft in the rotation through hole.

[0011] Optionally, an operation port communicating with the rotation through hole is further formed on the hinge portion. One end face of the stop shaft connected to the second rotating shaft is exposed at the operation port. A tool is inserted into the operation port to abut against one end face of the stop shaft connected to the second rotating shaft and an external force is applied to axially move the rotating shaft in the rotation through hole.

[0012] Optionally, the panel includes an installation cavity. When the cover body rotates relative to the panel to the closed state through the rotating shaft, the cover body is clamped in the installation cavity.

[0013] Optionally, an opening portion is provided on one side of the cover body opposite to the rotating shaft. A slotted groove matching the opening portion is provided on the side wall of the installation cavity. At least a part of the opening portion is located outside the panel, and the cover body is opened by applying an external force to the opening portion.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. When an external force acts on the rotating shaft of the dust-proof cover of the present utility model, it axially moves within the rotating through-hole, causing the second rotating shaft to disengage from the corresponding locking hole, and enabling the cover body to disengage from the connection with the panel. The cover body can be detached from the panel. The original cover body or the newly replaced cover body can be installed on the panel by inserting and connecting the first rotating shaft and the second rotating shaft with two locking holes, solving the problems that the currently used dust-proof cover, after being assembled at the factory, is affected by external conditions at the end-user site, resulting in the cover body falling off the panel under violent conditions, being unable to be disassembled and reinstalled, and the cover body being damaged under violent conditions, unable to be disassembled and replaced, thus affecting the overall product protection.

[0016] 2. The rotating through-hole of the present utility model is a stepped hole. The stop shaft, the second rotating shaft, the spring and the torsion spring are arranged inside the large-diameter end of the stepped hole. At least part of the first rotating shaft passes through the small-diameter end of the stepped hole and is inserted and connected with the corresponding locking hole. The blocking part is the stepped surface of the stepped hole and abuts against one end of the spring. This structural design can prevent the rotating shaft, the spring and the torsion spring from axially disengaging from the rotating through-hole, thereby ensuring that the cover body will not fall off the panel, ensuring that the panel is always sealed and protected by the cover body, and thus ensuring electrical safety.

[0017] 3. An operation port communicating with the rotating through-hole is further opened on the hinge part of the present utility model. One end surface of the stop shaft connected to the second rotating shaft is exposed in the operation port. A tool is inserted into the operation port from the panel to abut against one end surface of the stop shaft connected to the second rotating shaft and apply an external force to axially move the rotating shaft within the rotating through-hole. The design of the operation port facilitates the disassembly of the cover body from the panel using a tool, making the disassembly more intuitive, convenient and fast, and improving the disassembly speed.

[0029] Now, various exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present utility model and its application or use.

[0031] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0032] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0033] According to the first aspect of the present utility model, as Figures 1-7As shown in the figure, a dust cover is provided, which is arranged on the panel 2 of the charging / discharging gun or the charging base and is used to shield the panel 2. The dust cover includes a cover body 1, a rotating shaft 3, a spring 4 and a torsion spring 5. One side of the cover body 1 is provided with a hinge portion 11, and a through rotating through hole 111 is arranged in the hinge portion 11. At least part of the rotating shaft 3, the spring 4 and the torsion spring 5 are located in the rotating through hole 111. Two opposite locking holes 21 are arranged on one side of the panel 2. The two ends of the rotating shaft 3 are respectively inserted and connected with the two locking holes 21 to hinge-connect the cover body 1 to the panel 2. The rotating shaft 3 includes a stop shaft 31 and a first rotating shaft 23 and a second rotating shaft 33 axially extending from opposite ends of the stop shaft 31 respectively. The spring 4 and the torsion spring 5 are respectively sleeved on the first rotating shaft 23 and the second rotating shaft 33, and blocking portions for blocking the spring 4 and the torsion spring 5 from detaching are arranged at both ends of the rotating through hole 111. The depth of the locking hole 21 corresponding to the first rotating shaft 23 is greater than or equal to the lengths of the first rotating shaft 23 and the second rotating shaft 33 in the corresponding locking hole 21. Under the action of an external force, the rotating shaft 3 axially moves in the rotating through hole 111, and the second rotating shaft 33 is separated from the corresponding locking hole 21, so that the cover body 1 is separated from the connection with the panel 2.

[0034] With the rapid development of new energy vehicles, a waterproof and dustproof dust cover is provided on the panel 2 of the charging gun, discharging gun or charging base for new energy vehicles. After the currently used dust cover is assembled at the factory, at the end customer, it is affected by external conditions, resulting in the dust cover falling off the panel 2 under violent conditions or being damaged, and it cannot be disassembled and reinstalled secondarily or disassembled and replaced with a new cover body 1, resulting in the protection of the overall product being affected.

[0035] Under the action of an external force, the rotating shaft 3 of the dust cover of the present utility model axially moves in the rotating through hole 111, and the second rotating shaft 33 is separated from the corresponding locking hole 21, so that the cover body 1 is separated from the connection with the panel 2. The cover body 1 can be disassembled from the panel 2. The original cover body 1 or the newly replaced cover body 1 can be installed on the panel 2 by inserting and connecting the first rotating shaft 23 and the second rotating shaft 33 with the two locking holes 21, solving the problem that after the currently used dust cover is assembled at the factory, at the end customer, it is affected by external conditions, resulting in the cover body 1 falling off the panel 2 under violent conditions and being unable to be disassembled and reinstalled secondarily, and the cover body 1 being damaged under violent conditions and being unable to be disassembled and replaced, resulting in the protection of the overall product being affected.

[0036] In some embodiments, such as Figure 2 and Figure 4As shown, the rotation through-hole 111 is a stepped hole. The stop shaft 31, the second rotating shaft 33, the spring 4, and the torsion spring 5 are arranged inside the end with a larger diameter of the stepped hole. At least a part of the first rotating shaft 23 passes through the end with a smaller diameter of the stepped hole and is inserted and connected to the corresponding locking hole 21. The blocking portion is the stepped surface of the stepped hole and abuts against one end of the spring 4.

[0037] The stepped hole can prevent the rotating shaft 3 from axially falling off from the rotation through-hole 111, thereby ensuring that the cover 1 will not fall off from the panel 2, ensuring that the panel 2 is always sealed and protected by the cover 1, and thus ensuring electrical safety. The stepped surface of the stepped hole abuts against one end of the spring 4, which can limit the spring 4 in the state of being sleeved on the first rotating shaft 23 in the rotation through-hole 111 all the time.

[0038] In some embodiments, as Figure 4 and Figure 5 shown, the torsion spring 5 includes a spring body 51, a first torsion arm 52, and a second torsion arm 53 connected to the spring body 51. The spring body 51 is located inside the end with a larger diameter of the stepped hole. The blocking portion further includes a clamping groove 113 arranged on the hinge portion 11 and extending circumferentially. The clamping groove 113 communicates with the rotation through-hole 111. The first torsion arm 52 and the second torsion arm 53 extend out from the clamping groove 113 and limit the axial movement of the torsion spring 5 in the rotation through-hole 111.

[0039] The clamping groove 113 restricts the axial movement of the torsion spring 5 in the rotation through-hole 111, thereby restricting the rotating shaft 3 from disengaging from the rotation through-hole 111 at one end of the second rotating shaft 33, resulting in the cover 1 falling off. Coupled with the stepped hole that can restrict the rotating shaft 3 from disengaging from the rotation through-hole 111 at one end of the first rotating shaft 23, it is ensured that when the spring 4 is in a natural extended state, the rotating shaft 3 does not move around in the rotation through-hole 111, ensuring that both ends of the rotating shaft 3 are always locked with the corresponding locking holes 21, ensuring the stable connection between the cover 1 and the panel 2, and enabling the panel 2 to be always sealed and protected by the cover 1.

[0040] In some embodiments, as Figure 5 shown, an installation groove 114 is further formed on the hinge portion 11 from the outside of the hinge portion 11 to the clamping groove 113. The installation groove 114 communicates with the rotation through-hole 111. The first torsion arm 52 and the second torsion arm 53 enter the clamping groove 113 from the installation groove 114.

[0041] The addition of the installation groove 114 facilitates the sleeving of the torsion spring 5 onto the second rotating shaft 33 in the rotation through-hole 111, or facilitates the installation of the rotating shaft 3 sleeved with the torsion spring 5 and the spring 4 into the rotation through-hole 111, and also facilitates the removal of the torsion spring 5 from the second rotating shaft 33 via the clamping groove 113 and the installation groove 114.

[0042] In some embodiments, as Figure 4 shown, the inner hole of the spring body 51 and the second rotating shaft 33 are in clearance fit.

[0043] The inner hole of the spring body 51 and the second rotating shaft 33 are in clearance fit. The design of the clearance is for two purposes. One is to prevent the spring body 51 from hindering the movement and rotation of the second rotating shaft 33. The other is to avoid interference and friction with the second rotating shaft 33 during the process of the torsion spring 5 driving the cover body 1 to pivot, which is beneficial to pivoting, protects the spring body 51 and the second rotating shaft 33 from being damaged, and increases the overall service life of the dust cover.

[0044] In some embodiments, as Figure 4 shown, the spring 4 is a compression spring 4. One end of the spring body 51 opposite to the first torsion arm 52 and the second torsion arm 53, and the other end of the spring 4 are respectively abutted against opposite ends of the stop shaft 31.

[0045] This structural design can not only limit the spring 4 in the rotation through hole 111 in the state of being sleeved on the first rotating shaft 23 to prevent the spring 4 from axially moving in the rotation through hole 111, which is convenient for the disassembly and installation of the cover body 1, but also limit the torsion spring 5 in the rotation through hole 111 in the state of being sleeved on the second rotating shaft 33 to prevent the torsion spring 5 from axially moving in the rotation through hole 111, which is also beneficial to the stable pivoting of the cover body 1 relative to the panel 2.

[0046] In some embodiments, as Figure 6 shown, the locking hole 21 corresponding to the second rotating shaft 33 is a through hole. A tool is inserted into the through hole to abut against the second rotating shaft 33 and an external force is applied to axially move the rotating shaft 3 in the rotation through hole 111.

[0047] The design of the through hole facilitates inserting into the through hole to abut against the second rotating shaft 33 and applying an external force, so that the first rotating shaft 23 axially moves into the through hole. The through hole has sufficient length for the first rotating shaft 23 to extend in, so that the second rotating shaft 33 of the rotating shaft 3 axially moves in the rotation through hole 111 until it completely disengages from the locking of the locking hole 21, and the cover body 1 is disengaged from the connection with the panel 2, making the disassembly operation more intuitive, simple, convenient and fast, and improving the disassembly speed.

[0048] In some embodiments, as Figure 1 and Figure 5As shown, an operation port 112 communicating with the rotation through hole 111 is further formed in the hinge portion 11. One end surface of the blocking shaft 31 connected to the second rotating shaft 33 is exposed in the operation port 112. A tool is inserted into the operation port 112 to abut against one end surface of the blocking shaft 31 connected to the second rotating shaft 33 and an external force is applied to axially move the rotating shaft 3 in the rotation through hole 111.

[0049] The design of the operation port 112 facilitates the removal of the cover body 1 from the panel 2 using a tool, making the removal operation more intuitive, simple, convenient and fast, and improving the removal speed.

[0050] In some embodiments, as Figure 5 and Figure 7 shown, the panel 2 includes an installation cavity 22. When the cover body 1 rotates relative to the panel 2 to the closed state through the rotating shaft 3, the cover body 1 is snap-fitted in the installation cavity 22.

[0051] The cover body 1 is snap-fitted in the installation cavity 22, which plays a role in sealing and protecting the panel 2, preventing the panel 2 from being knocked by the outside world, and blocking the entry of outside water vapor and impurities into the panel 2, resulting in electrical safety problems.

[0052] In some embodiments, as Figure 7 shown, an opening portion 12 is provided on the side of the cover body 1 opposite to the rotating shaft 3. A slot 23 matching the opening portion 12 is provided on the side wall of the installation cavity 22. The opening portion 12 is at least partially located outside the panel 2, and the cover body 1 is opened by applying an external force to the opening portion 12.

[0053] The provision of the opening portion 12 facilitates the cover body 1 to pivot relative to the panel 2 to the open state by applying an external force to the opening portion 12, so that the panel 2 is exposed outside, facilitating the subsequent plug-in connection for charging / discharging.

[0054] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for the purpose of illustration and not for the purpose of limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
